A Review on the Matrix Toughness of Thermoplastic Materials

elastic stiffness and strength of metals can be increased and large coefficients of thermal expansion and thermal and electrical conductivities of metals can be reduced, by the addition of fibers such as silicon carbide. Metal matrix composites are mainly used to provide advantages over monolithic metals such as steel and aluminum.
